Abstract Objective The American College of Surgeons (ACS) encourages clinicians to provide training to laypeople on tourniquet application. It is unclear whether clinicians are confident in their abilities and equipped with adequate knowledge, skills, and resources. This study aimed to determine surgical trainee knowledge and attitudes regarding tourniquet application and compare the effectiveness of instructions. Methods Thirty surgical trainees performed a tourniquet application simulation using a Combat Application Tourniquet and one of the three instructions sets developed by ACS, Department of Homeland Security, and the tourniquet manufacturer. Participants reported tourniquet knowledge, attitudes, and confidence and discussed the instructions. One instruction set was updated and compared to the original set with 20 new trainees. Results Participants with ACS instructions passed the greatest number of steps (p < 0.01) and completed the task significantly faster compared to those with manufacturer instructions (p < 0.01). Participants (80%) reported favorable views toward tourniquets but 30–60% did not align with to ACS tourniquet guidelines. Focus group participants suggested revisions to the ACS instructions. Comparing the original and revised version of these instructions resulted in no significant improvements. Conclusions ACS instructions provide guidance; however, improvements to tourniquet instruction are needed for success in controlling exsanguinating hemorrhage.

Periodic intraoperative microbreaks with calesthenic exercises performed within the sterile field improved self-reported mental focus (38%) and physical performance (57%) for 56 surgeons. Therefore, targeted stretching exercises and a web-application (web-app) leading the stretches with a reminder system were developed and piloted using user-centered design principles. A focus group with 10 users was conducted to refine the developed app. Seven surgeons (4 females) at a quaternary medical institute piloted the periodic stretching web-app in their operating rooms. At the end of each surgical day, the surgeons completed a short survey about the intraoperative stretching exercises web-app impact on their physical performance, mental focus and workflow disruption. Non-Routine Events were captured during the procedures. Twelve surgical days were followed with a median of 6 microbreaks/day/surgeon. Results showed that better physical performance and lower fatigue were reported (91.7%) across the surgical days, also better mental focus was reported (83.3%) across the surgical days, and less pain/discomfort was reported (100%) across the surgical days, with others reporting no change. The web-app leading sterile field microbreak stretches helped reduce physical pain, discomfort/pain, fatigue, and improve mental focus with minimal disruption for a small sample. The web-app is a promising tool for improving surgeon mental focus and physical performance and potentially musculoskeletal health.

The aim of this study was twofold—(1) to compare the current ED staffing workload alert system to clinicians’ perceptions of workload in the ED, and (2) to examine the potential impact of a multi-faceted, systems-level intervention on clinicians’ perceptions of workload. Constant flow of patients into the Emergency Departments (ED) regularly increases the workload of clinicians and can compromise the quality of care delivery and patient safety. An automatic staffing workload alert system was created and implemented in response to an observed shift in patient volume to the overnight hours at one academic quaternary care center. Surveys addressing workload and interruptions were administered to ED clinicians, pre-and post-intervention implementation. Output from the staffing workload alert system was recorded for each clinician shift. Clinicians’ perceptions of workload were able to predict swing shift activations, χ 2 (6) = 14.14, p = 0.028. Only the performance subscale significantly correlated with swing shift activations, p=0.006. A Kruskal-Wallis H test found perceived interruptions changed following systems-level changes, χ 2 (1) = 7.195, p = 0.007. Utilizing subjective measure of clinicians’ workload validated an objective, automated staffing workload alert system that determined if swing shift activations are necessary.

Interruptions in the emergency department (ED) have been studied across multiple clinical roles, with little investigation into how residents experience interruptions. Therefore this pilot study aimed to characterize interruptions experienced by emergency medicine (EM) residents at various post-graduate year (PGY) levels. Observers shadowed ED residents across entire shifts and logged interruptions that affected clinicians into the Workflow Interruption Tool (WIT). Interruption characteristics captured included duration, nature, location, and task priority. Chi-square analysis identified a significant association between interruption type and the interruption priority, p < 0.001. Residents at varying PGY-levels experienced significantly different amounts of interruptions, p=0.013. Observing resident interruptions across the entirety of their shifts identified that as EM residents gain more experience, they are interrupted more often while working in the ED.

The high uncertainty of the emergency department (ED) and intermittent time-critical activities creates unpredictable staff workloads. Frequent interruptions are inherent to this acute care work environment adding to the demands placed on clinicians. Implementing sustainable interventions to mitigate interruptions has been a challenge. This study examined interruptions in the emergency department and provides a methodology for co-creating interventions to eliminate and/or manage interruptions impact on the care process. Observers collected and categorized interruptions using a validated tablet PC-based tool during clinicians’ entire shifts. Focus groups were used to develop and select provider-centered interventions. A total of 7889 interruptions were identified across 91 shifts. A total of 24 interventions were selected for potential implementation. The interventions were related to (1) protocol, procedures and policy, (2) information sharing, (3) devices and (4) role clarity. Developing sustainable solutions to interruptions has the potential to reduce patients’ vulnerability.

Interruptions in the Emergency Department (ED) are moderately studied in regard to their impact on physicians’ workload. This study captured interruptions characteristics and measures of workload. Twenty-eight ED physicians were followed during their shifts; interruptions they faced were captured using a validated tablet PC-based tool. At the mid and end of their shift, providers completed a NASA-Task Load Index (TLX) questionnaire and a reaction time task. Descriptive statistics and ANOVA were used to identify relationships between physicians’ interruptions and workload. A total of 2355 interruptions were identified ( M =84.1, SD =14.5). The NASA-TLX results showed increase in physicians’ responses for all subscales from mid to end-shifts. Reaction time was higher at end-shift with mean difference of 33.75ms, 95% CI [20.35, 47.13], p < 0.001. At end-shift, there was a statistically significant positive correlation between reaction time and all NASA-TLX subscales. Interruption duration rather than frequency correlated positively with NASA-TLX scores. High/critical interruptions were the least frequent but had longer duration and greater impact on workload. This study provided a unique examination of interruptions over an entire provider shift and identified interruptions as potential causes of increased workload for ED physicians.

Clinicians have anecdotally indicated that interruptions increase following trauma activations in the emergency department (ED), yet it is unknown whether interruptions change following the end of a trauma case. This study aimed to examine the interruption characteristics of clinicians that participate in trauma activations before and after activations using the SEIPS model. Observers shadowed ED clinicians across entire shifts and logged interruptions that affected clinicians in a tablet PC-based tool. Interruption characteristics captured included duration, nature, location, and task priority. Trauma activations lasting more than five minutes were also recorded. Only interruptions occurring within one-hour of trauma activations were included in the analysis. Chi-square analyses identified significant associations between SEIPS-categorized interruptions and the interruption priority, p < 0.01, and between the SEIPS-categorized interruptions and the interruption location, p = 0.01, pre- and post-trauma activations. Identifying these associations revealed key opportunities to reduce unnecessary interruptions in the ED.
